CHARLES WV. FISHER, OF BALTIMORE, MARYLAND, ASSIGNOR OF ONE-HALF TO JACOB S. DETRICK, OF SAME PLACE.

HOLDER FOR swmon e SCAFFOLDS.

SPECIFICATION forming part of Letters Patent No. 414,634, dated November 5, 1889.

Application filed May 7, 1889. Serial No. 309,923- (No model.)

Be it known that 1, CHARLES \N. FISHER, a citizen of the United States, residing at Baltimore, in the Stateof Maryland, have invented certain new and useful Improvements in Holders forSwinging Scaffolds, of which the following is a specification.

This invention relates to a device for holding painters swinging scaffolds, and is illustrated in the accompanying drawings, in whicl1- Figure 1 is a vertical section of a house-wall through a windowy-and also shows the swinging scaffold and improved holdingbar. Fig. 2 is a horizontal section of a house-wallgthrough a window, and shows the holding-bars applied thereto and .to the scaffold. Figs. 3 and 4 are side and top views, respectively, of the holding-bar and clamp device.

The scaffold A, by means of a'rope b, is suspended, as usual, at the side of a house-wall O. This is the rig used by painters. My invention has for its object to hold such scaffolds from swinging. To this end I provide a metal bar D, having at its extremity a lateral point or hook e, which is adapted to take into the back of the wood frame F of the window, as shown in Fig. 2. By having a slight bend 9 near the end of the bar, as shown in Fig. 4, so that the end part it projects obliquely'therefrom, the said outer angle of the bond will serve to bear against the brick-work of the window-opening, which'will enable the bar to be used as a lever, and thereby force the metal point or hook e into the wood window-frame sufficient to engage the bar therewith.

The bar D, having provision at one end for engagement with the window-frame, is secured to the hanging scaffold A in any suitable or convenient manner. Two or more holding-bars should preferably be employed. In the present instance two bars are shown attached to one window-frame, though ordinarily each bar would be attached to aditferent window-frame. By the combination with a hanging scaffold of this holding-bar having a lateral hook the said scaffold will be pre vented from swaying or moving.

A clamp I is employed to secure the holding-bar D to the scaffold A. This clamp is readily adjustable both along the bar D and also as to its dimension to take around the ladder-rail. The clamp in the present instance forms a yoke or clip, which takes around one of the rails of the ladder or soaffold. The construction of the clamp may vary; but, as here shown, one plate has two eyes it, through which the holding-bar passes loosely. This plate forms part of the clamp, and the other parts are attached to it. A right-angled adjusting-bar has one arm It passed loosely through a hole 1 in the said plate. The same arm also crosses the holding-loar D, and the other arm 70 is parallel with the plate 3'. A pin m, passed through the arm and bar D, serves to confine the clamp to the said bar. This arm has several holes m, and the barD also has severalholes 71, whereby provision is made for adjustment by means of the pin m. The two parallel parts j 10 take on opposite sides of one of the scaffold-rails, and a pin 0, passed through the said two parts, confines the clamp to the scaffold-rail.

Having described my invention, I claim- 1. In a swinging scaffold, the combination therewith of a holding-bar D, having near the end abend g, and the end part 71. beyond the bend projecting obliquely and provided at its extremity with a lateral hook e, to engage with the window-frame 8o 2. The combination of a swinging scalfold,

a holding-bar having at its extremity a hook, and aclanip which takes around one of the rails of the scaffold for securing and adjusting the holding-bar.

In testimony whereof I affix my signature in the presence. of two. witnesses.
